• Stateful Inspection Firewall
Monitors active connections and determines which traffic to allow based on connection state.
• Next-Generation Firewall (NGFW)
Combines traditional firewalls with additional features like deep packet inspection and intrusion prevention.
• IDS (Intrusion Detection System)
Monitors network traffic for suspicious activity and alerts administrators.
• IPS (Intrusion Prevention System)
Similar to IDS, but actively blocks threats in real-time.

MFA (Multi-Factor Authentication)

Requires multiple forms of verification (e.g., password + code from app) for user access.

• OAuth

An authorization protocol allowing third-party apps to access user data without revealing passwords.

• SAML (Security Assertion Markup Language)

Used for single sign-on (SSO), enabling identity federation between services.

• RADIUS / TACACS+

Protocols for centralized Authentication, Authorization, and Accounting (AAA) of users.

--WPA2 / WPA3 (Wi-Fi Protected Access)

These are modern security standards designed to protect your wireless network from unauthorized access.

WPA2 offers robust encryption (AES) and is still widely used.

--WPA3, the latest version, introduces stronger protection even on public networks and against brute-force attacks.

Together, they encrypt data, verify user access, and ensure your business Wi-Fi remains private and secure.

EAP (Extensible Authentication Protocol)

EAP is a flexible authentication framework used with WPA2/WPA3 Enterprise networks.
 

It supports advanced login options such as:

Username and password

Smart cards

Certificates

EAP ensures that only authorized users and devices can connect to your network—making it ideal for enterprise-level Wi-Fi security where identity and role-based access control are critical.

-- AES (Advanced Encryption Standard)
A widely trusted symmetric encryption algorithm used by governments, businesses, and cloud platforms.
AES protects data both at rest (stored files) and in transit (during transmission) by using a single key to encrypt and decrypt information.
It’s fast, secure, and forms the backbone of modern data protection.
--RSA (Rivest–Shamir–Adleman)
A powerful asymmetric encryption algorithm that uses two keys — one public, one private — to protect data.
RSA is commonly used in digital signatures, SSL certificates, and secure online transactions.
It ensures that sensitive data stays confidential, even across untrusted networks.

--Security Policies
These are the formal rules and procedures that define how your organization protects its data, systems, and users.
They outline access controls, password standards, incident response plans, and compliance requirements.
Effective policies ensure that everyone follows the same security expectations.
--Security Audits
A systematic review of your IT environment, including networks, devices, and configurations.
Audits help identify security gaps, misconfigurations, or outdated software that could lead to breaches.
They’re essential for maintaining regulatory compliance and best practices.
--Penetration Testing
Also known as ethical hacking, pen testing simulates real-world cyberattacks to test how secure your systems really are.
Security professionals attempt to exploit vulnerabilities just like a hacker would, then report what they find.
This proactive approach helps fix weaknesses before attackers can find them.
